BCW-P is composed basically by capacitors UCW, CWM_C contactors for switching capacitive loads, electronic timer relay RTW-RE to avoid resetting of capacitors on load and mouldedcase circuit breaker or retard fuses for short circuit protection.
Characteristics:- Discharge resistor incorporated; - “Open Box” system for easy maintenance; - Electronic timer relay to protect against resettings; - Installation on vertical position.
Applications:- Power factor correction of individual loads and motors; - Automatic banks.
(1) For others voltages and frequency please contact your local WEG office or Agent.(2) All cables sized according with Ir×1,43 and average ambient temperature of 30ºC. (3) Power cables not supplied with BCW-P.(4) The Protection type must be selected: F(Retard Fuse) or D(Moulded Case Circuit Breaker)
The over pressure disconnector device will disconnect the capacitive element from power source when happen an overload avoiding explosion risks.

The motors power factor correction can be calculated through this formula: Qcapm=
%Load = Power factor according Load factor applied in motor. E.g.: Motor operating at: 50% → P =0, 5, 75% =0, 75 and 100% =1. P = Active power (W);F = Multiplication factor according to the table above;η = Motor efficiency; Qcapm = Reactive power necessary to the motor (kVAr)
To calculate the reactive power using energy bills it is recommended to do an average of consumption over a minimum 12 months billing period. The mean values obtained for power factor and active power calculated must be used with required power Factor (F).E.g. (1): Average current power factor (CPF) = 0, 8Average active power factor (AP) = 1000kWRequired power factor (RPF) = 0, 92Multiplication factor according to the table above (F) = 0,324KVAr = AP x F = 1000 x 0,324 = 324kVAr(1) Always analyzes the load types installed and load installation curves.
Notes: - If 20% of total loads are not linear (frequency inverters, soft-starters, rectifiers, electronics reactors, etc) inductive reactors anti-harmonics must be installed. - Harmonics distortions limits: DHV (Voltage) < 5% and DHA (Current) <15%- Capacitor use in electrical systems with high level of harmonic distortion can damage internally the capacitive cells.
